DETACI-IABLE TIRE-HOLDING RING.

Specification of Letters Patent. Patented NOV, 30, 1915.

application filed December 19, 1911. Serial No. 665,831.

To all whom it may concern:

Be it known that I, VILLIAM N. BOOTH, a citizen of the United States, and resident of Detroit, in the county of WVayne and State of Michigan, have invented certain new and useful Improvements in... Detachable Tire- Holding Rings, of which I hereby declare the following to be a. full, clear, and exact description, such as will enable others skllled in the art to which it appertains to make and use 'thesame.

The objects of the invention are to provide a detachable tire holding split ring to be used in connection with a tire rim, and so constructed as to be simple in construction matic tire upon the rim.

This device is an improvement upon the device described in my former applications Ser. Nos. 605,528 and 595,816, for a quick detachab'le'ring, in this respect that a separate locking ring is dispensed with and the tire holding ring is itself split and expanse ble to release the tire and is provided with means for bringing the ends closely together upon the tire and for releasing the ends when it is desired to remove the tire.

The invention comprises the combination and arrangement of parts and construction of the clamping means as hereinafter de scribed, shown in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a longitudinal section showing the extremities of the ring in the locking position and showing the clamping device in the closed position and in dotted lines the clamping member is shown in the released position; Fig; 2 is a plan view of the clamping device from the inner side of the rim; Fig.-

3'is a transverse section of the rim and spring locking ring; Fig. 3 is a transverse section of rim showing tire holding rings arranged for a straight sided tire; Fig. 3 is? a similar section showing the holding rings arranged for a clencher tire; Fig. l-is inside elevation of the ring and Figs. 5 and (S are detailed views in elevation of the respective ends of the ring.

In these views 1 represents the sheetmetal I rim for the tire, 2 represents the marginal annular slot therein in which is secured thev annular flange or tongue 4 'whichjisintegral Upon the outer edge of the rim is shown the fiange'G corresponding in curvature to the locking ring. Upon one side of the tire rlm arenarrow longitudinal slots 7 and 8 7 or 8 and the thickness ofithe flange or tongue 3 is less than the thickness of the slot in which it lies, so that the projections at the extremities of the ring can easily be passed i 11 is beveled at 16 on its inner face so asqto pro ect radially through its respective slot through these openings or removed there- I from. The extremity 11 shown at the right of Fig. 1 is of less width than the length of.

the slot 8 so that it can be removed from its secul'ed position and lastly the projection 10 is removed from its locking position.

retain these parts'in position the projection 11 is cut away in circular form at the angle where it joins the tongue or flange &, and a clamping lever L pivoted on the inner face of the ring at the left of the opening "9 shown in Fig. 1, extends upon both sides of the projections 10 and 11 and is provided with pivoted pawl L which can be forced bacl'cward between "the edge ofv the projection lland the edge if of the rim and-Will engage at this outer end with the'recess before mentioned at the angle of junction of said projection with the flange or tongue 3 thus holr ling the parts rigidly in position. hen the tire is inflated upon this rim the extremities of the ring will be moved apart and the pawl L will be forced against the edge L of the rim, and the projection 10 and a shoulder L upon the projection 10' which will engage forcibly with the edge L of the rim, thus preventing the parts fromunlock'ing themselves. The pawl is provided with a shoulder at its lower end L to prevent it from falling backward into the lever which is made hollow so as to inclose the two projections 10 and 11 and prevent the entrance of dust into the openings 7 and 8. This lever is preferably formed of sheet metal folded upon itself to inclose the sides of the lever.

sorted to force the that the pawl-Candie released from its edge thereof,

I with elongated pawl, to the folded and the pawl is pivoted at L ring is. provided withan opening O into whielnthe extremities of the lever can "be 111 parts together again, so

positlon by droppingthe lever as shown in dotted lines in Fig 1. When this has been 210- complished by inserting a suitable tool underneath the end of the projection. 11 it can be sprung to clear the edge of the rim, and. the ring can be easily removed to replace the tire upon the rim. ny variety of tool suitable for this purpose can be employed, which need not be described herein.

Having described the invention what 1 claim as new and desire to secure by Letters I Patent is:

lever adapted to engage said projecting por-- tions on'said'ring when said ring is closed and adevice at one extremity of said lever insertiblethrough one of said slotted openings, adapted to engage and retain 'one of said projections in the locking position.

Each extremity of the 'tion between .ring, the extremities of 2. The combination with a rim, of a split tire locking ring thereon, said rim provided. with slotted openings and an integral porsaid openings and said ring provided. with projecting portions adapted to pass through said clamping devicepivoted on said rim and adapted to overlap said integral portion, and means pivoted to said clarn 'iing device for detachably securing one or" said ring tremities in place the extremities of said ring interlocking with said rii'n between said openings therein.

3. The combination with rim provided with a circumferential marginal slot and with slotted openings in the base of said marginal slot and an integral portion sepa rating said openings, of a split tire holding ring provided with an annular riange adapted to enter said circumferential slot in said said tire holding ring provided with inwardly projecting extensions slotted at their ends to inclose said integral member between them, one of said extremities provided with a recess on its inner face, a lever pivoted adjacent to one of said slotted openings and extending over both of them, and a pawl pivoted in the outer end of said lever and adapte to pass through one of said openir-" and to ei'sgoge the recessin its adjacent ex *einity.

In, testimony whereof. I hereunto set my hand this 20" day of November; 1911.
